I had to change 3 of my tires in about a month due to potholes (2 fronts and 1 rear). Would it be advisable to replace the 4 tire as well? Im just learning
about rolling diameter and from my understanding all 4 tires should be equal in circumference.

Thanks in advance

That really depends on how much tread is left in the old tire. Tread depth gauges are quite cheap at Walmart. Go from there...
